Been there and done that but I would have made sure she looked by asking her If she wanted some cock.The other group of girls seemed like they saw enough.I've flashed hundreds of time so I've seen girls like this where It's funny to them and they won't even tell the girl your jacking off to.By the way they were acting I'd say they at least saw some of It.Good job but be careful about doing It on a busy street like that was.I actually had a police car drive by me one time and stop.It's never fun trying to out run the cops which I did that day.Be more careful or you'll get caught.
